Camunda Rest API

Hello,

Myself is Asha CM from India.

We have developed a web application with 3 tier architecture. Database in Postgres, Middleware in DjangoRestFramework and UI in HTML/CSS/js (Codeignitor Framework)

I wish to integrate Camunda to our application . I am confused in the way i have to start with.

Shall i go with ,

  1. Camunda Rest API OR
  2. External Tasks

For ex. I have the accounts module. Currently a receipt is generated on form submit. Soon after the receipt creation i wish to move to the task , receipt verification after that task completion.

How to handle this scenario .
